This product is excellent! Almost all necessary minerals, vitamins and more in one. It's easy to ingest. It seems well produced, never gave me any troubles, even on empty stomach. One could add a B-/A-/D-Vitamin supplement if necessary, because it's not present/not enough in that product. In my opinion it's the best value you can get.

My doctor recommended I start taking calcium and Vitamin D supplements during my year check-up. I first bought this product at my local (expensive) health food store but decised to search the net for better prices.
iHerb has competitive pricing on their products and I would recommend trying them out to see how much you can save by shopping here!
As for the supplement, only time will tell I guess but it doesn't upset my stomach (but do take them with food!) and they are pretty easy to swallow given their size.
